EXPERIMENTS 1
K or P?
TYPES OF ENERGY
EXPERIMENTS 2
100
Burning a candle. (2 steps)
Chemical energy -> heat energy + light energy
100
SOMETHING THAT STAYS THE SAME THROUGHOUT THE EXPERIMENT
WHAT IS A CONSTANT IN AN EXPERIMENT?
100
What is the process of saving up or storing energy?
Potential energy.
100
Energy that has the ability to fall; this type of energy increases the higher up you go.
Potential (gravitational) energy.
100
THE VARIABLE THAT DOES NOT CHANGE SO IT CAN BE COMPARED TO THE OTHER FACTORS IN THE EXPERIMENT
WHAT IS A CONTROL IN AN EXPERIMENT?
200
Using a hot plate to boil water. (2 steps)
Electrical energy -> heat energy
200
BY FORMING A CONCLUSION THAT IS SUPPORTED BY DATA
HOW DO YOU CONDUCT A SCIENTIFIC INVESTIGATION?
200
What is energy in motion.
Kinetic energy.
200
"You can burn it or you can eat it."
Chemical energy.
200
THE FACTOR THAT IS CHANGED PURPOSELY AND CAUSES THE OTHER VARIABLE TO CHANGE
WHAT IS AN INDEPENDENT VARIABLE?
300
A hungry football player eating a large sandwich to use the food for energy. (2 steps)
Chemical energy -> mechanical energy
300
A FACTOR THAT PURPOSELY CHANGES AND CAUSES OTHER VARIABLES TO CHANGE
WHAT IS A TEST (INDEPENDENT) VARIABLE?
300
A heavy vase on a table has this type of energy.
(Gravitational) potential energy.
300
This type of energy is generated by a force - a push or a pull. Object is moving due to the force.
Mechanical energy.
300
THE FACTOR THAT IS AFFECTED BY THE OTHER VARIABLE
WHAT IS THE DEPENDENT VARIABLE
400
Using a solar-powered calculator. (3 steps)
solar energy -> electrical energy ->light energy
400
AN EDUCATED GUESS BASED ON PRIOR KNOWLEDGE AND EXPERIENCE
WHAT IS A HYPOTHESIS?
400
A person running down the sidewalk has this type of energy.
(Mechanical) kinetic energy.
400
The energy of moving particles.
Heat (thermal) energy
400
EXPERIMENTS THAT ARE DONE OVER AND OVER CONSTANTLY
WHAT ARE REPEATED EXPERIMENTS?
500
A solar panel on the roof of a building used to heat and cool the building. (2 steps)
solar energy -> electrical energy
500
AN EXPERIMENT WHERE ONE VARIABLE IS TESTED AT A TIME
WHAT IS A CONTROLLED EXPERIMENT?
500
A person that has just jumped from an airplane has this type of energy. Explain!
potential and kinetic energy.
500
The energy of moving electric charges.
Electrical energy
500
